CEAと原子力機構の両者はナトリウム冷却炉の商用化を目指して相互に2020年代に実証炉を建設する計画がある。CEAはプール型炉、原子力機構はループ型炉を選択しているが今回相互評価を実施した結果両者とも技術的成立性があり、炉型に依存しない部分について広範囲な技術協力の可能性があることを確認した。

CEA and JAEA intend to develop prototype or demonstration (proto/demo) of sodium-cooled fast reactors within these two decades. Common final goals of their respective programs are SFR commercialization. The target of commercialized SFR for both parties is basically consistent with the Generation IV goals. Due to industrial backgrounds and feedback of past/existing reactor experiences, ASTRID and JSFR have selected pool and loop configurations respectively. CEA and JAEA have cross-analyzed both pool and loop concepts (ASTRID and demonstration JSFR). The analysis results showed that both concepts are technologically feasible and meet design goals. From the view point of collaboration, the present analysis has identified a wide range of collaborative items; they are described in the paper.
